Abstract
A valve for controlling a medium, e.g., a gaseous medium, includes: a valve support having at least one passage aperture; a closing element which is configured to open and to close the at least one passage aperture; and a valve seat including at least one area projecting in the axial direction of the valve, the projecting area being coated with an elastomeric sealing element, and the elastomeric sealing element being exclusively situated on the projecting area of the valve seat.
Description
- 1. Field of the Invention
- The present invention relates to a valve for controlling a medium, e.g., a gaseous medium, having an enhanced cold start capability.
- 2. Description of the Related Art
- Valves for controlling media are known in a variety of embodiments from the related art. In the motor vehicle field, gaseous fuels such as natural gas or biogas are being increasingly used in addition to liquid fuel. However, in particular the valves previously used for liquid fuels frequently do not meet the requirements of gas valves for gaseous fuels. A valve for gaseous hydrogen is known from Published German patent
application document DE 10 2010 043 641 A1, for example, in which three annular passages are situated in a valve seat support, which each have a web between each other. A height of the webs in the axial direction of the valve is smaller than a distance between an inlet opening and an outlet opening on the valve seat support. However, in particular the manufacture of this valve seat support is very complex and thus cost-intensive. In addition, manufacturers of gas valves in particular also have to design the gas valves for different engines of different engine manufacturers, in addition to the requirements of different gaseous media. In addition to high development complexity for the different variants, production also requires a wide variety of production lines to be installed, which makes the manufacture of such valves more expensive. - The valve according to the present invention, in particular a gas valve, for controlling a medium has the advantage over the related art that it is particularly cost-effective to provide and has an enhanced cold start capability, in particular at temperatures below 0° C. This is achieved according to the present invention in that the valve includes a valve seat which has a projecting area in an axial direction of the valve. The projecting area is coated with an elastomeric sealing element, the elastomeric sealing element being situated exclusively on the projecting area of the valve seat. According to the present invention, in this way only the relevant contact surfaces of the valve seat are provided with the elastomeric sealing element. Moreover, the idea according to the present invention provides a very robust design, and a modular and cost-effective construction is possible. Nonetheless the necessary sealing requirements may be met, in particular in the customary temperature range from −40° C. to +100° C., thus also solving the problem that exists in the related art of the immersion of the valve seat into an elastic sealing element, which may result in an increased contact surface between the sealing element and the valve seat.
- The elastomeric sealing element preferably has a small thickness in the axial direction of the valve. The thickness of the elastomeric sealing element particularly preferably ranges from 50 μm to 300 μm, in particular 100 μm to 150 μm. These ranges in particular ensure that an excessive adherence of the elastomeric sealing element in the closed state of the valve is prevented, even at low temperatures below 0° C.
- The valve seat is particularly preferably situated on the valve support. According to one alternative embodiment of the present invention, the valve seat is preferably situated on the closing element. It is thus possible according to the present invention to situate the valve seat including the projecting area only on one of the two components.
- It is further preferred if the elastomeric sealing element is applied to the valve seat with the aid of micro injection molding or with the aid of screen printing. These two methods allow the elastomeric sealing element to be applied very precisely and reliably to the valve seat, so that no undesirable overhang or the like is present on the valve seat. In this way a direct integral joint between the valve seat and the sealing element is achieved.
- It is further preferred if a height of the valve seat in the axial direction of the valve is in a range from equally as high to 3 times the thickness of the elastomeric sealing element in the axial direction.
- According to one further preferred embodiment of the present invention, the valve includes a planar closing surface which seals on the valve seat. In other words, the valve seat is provided on one of the two components that are the valve support or closing element and the other of the two components includes the planar closing surface. This not only ensures a simple geometry of the valve, but also that an immersion into the elastomer element is prevented.
- It is further preferred if the valve includes a stop which is formed between the valve support and the closing element. An exact deformation of the elastomeric sealing element is thus definable in the closed state of the valve.
- According to one further preferred embodiment of the present invention, the valve includes an intermediate element which is situated between the valve support and the closing element, the intermediate element including the valve seat. In this way in particular a high number of identical parts is made possible since the intermediate element in each case is also adaptable to the specific requirements, for example of a particular engine manufacturer. The intermediate element is particularly preferably a disk, in particular a stamped embossed part in the form of a disk. It is further preferred if a thickness of the intermediate element is approximately 2 to 3 times the thickness of the sealing element.
- The valve according to the present invention is preferably designed as a gas valve and is used to control in particular gaseous media, such as natural gas or biogas. The gas valve is particularly preferably an injection valve for injecting gaseous fuel into a combustion chamber.
- Preferred exemplary embodiments of the present invention will be described in greater detail hereafter with reference to the accompanying drawing. Identical or functionally equivalent parts are denoted by the same reference numerals.

FIG. 1 shows a schematic sectional view of a gas vale according to one first exemplary embodiment of the present invention. -
FIG. 2 shows a schematic sectional view of a valve support ofFIG. 1 . -
FIGS. 3 through 5 show additional preferred exemplary embodiments of gas valves according to the present invention. - A gas valve 1 according to one first exemplary embodiment of the present invention will be described in greater detail hereafter with reference to
FIGS. 1 and 2 . - Gas valve 1 of the first exemplary embodiment is an injection valve for injecting fuel into a combustion chamber. Gas valve 1 includes a
valve housing 10, anarmature 12, asolenoid 13 and aclosing spring 14. Asetting bolt 16 is provided to set a return force of closingspring 14. The gas is supplied in the axial direction (arrow H) and conducted through afilter 11.Solenoid 13 is fixed onvalve housing 10 in an extrusion coating made of plastic. Anelectrical plug connection 18 is provided laterally on gas valve 1. - A
closing element 3 is attached to an axial end ofarmature 12. Closingelement 3closes passage apertures 6 which are formed in avalve support 2.FIG. 1 shows the closed state of gas valve 1. Arrows G indicate a flow direction of the gaseous fuel when the gas valve is open, the gas being injected into a combustion chamber through aspace 19 invalve housing 10 and throughpassage apertures 6. A central aperture (seeFIG. 2 ), via which gas may also flow topassage apertures 6, is further provided inclosing element 3. - As is apparent from the enlarged detailed view of
FIG. 2 , a first valve seat including anarea 4 projecting in the axial direction X-X of the valve and a second valve seat including anarea 5 projecting in the axial direction X-X are provided onvalve support 2. Multiple kidney-shaped passage apertures 6 are situated between projectingareas - As is also apparent from
FIG. 2 , projectingareas elastomeric sealing element 7.Elastomeric sealing element 7 is provided exclusively on projectingareas elastomeric sealing element 7, so that a very good cold start capability of the valve is achieved. In particular no overhang or the like is provided, which would result in an increased contact surface of the sealing element with the closing element in the closed state. - A thickness of
elastomeric sealing elements 7 on projectingareas planar closing surface 20 is furthermore provided onclosing element 3, whereby it is prevented in the closed state that closingelement 3 can penetrate intoelastomeric sealing elements 7 and thereby a cold start capability of the valve is possibly worsened.Planar closing surface 20 ensures that, in the closed state of the valve, not only the tightness of the valve is ensured across all relevant temperature and pressure ranges, but also a maximally permissible pressure load of the elastomeric sealing element material continues to be adhered to. -
Elastomeric sealing elements 7, which are selectively applied only to projectingareas -
FIG. 3 shows a gas valve 1 according to a second exemplary embodiment of the present invention, which essentially corresponds to the first exemplary embodiment. Contrary to the first exemplary embodiment, astop 8 is additionally provided in the second exemplary embodiment.Stop 8 is formed by an annular protrusion on closingelement 3.Stop 8 ensures that a predefined deformation ofelastomeric sealing element 7 is always adhered to in the closed state under all operating conditions.Stop 8 is designed for this purpose as a metallic stop betweenvalve support 2 andclosing element 3. -
FIG. 4 shows a gas valve according to the third exemplary embodiment of the present invention. This exemplary embodiment essentially corresponds to the first exemplary embodiment; however, contrary to the first exemplary embodiment, the first and second valve seats having projectingareas element 3 in the third exemplary embodiment. Moreover,planar closing surface 20 is provided onvalve support 2. As in the preceding exemplary embodiments,elastomeric sealing elements 7 are formed only on projectingareas - Contrary to the preceding exemplary embodiments, an
intermediate element 9 is provided in the fourth exemplary embodiment shown inFIG. 5 .Intermediate element 9 includes the first and second valve seats having projectingareas Intermediate element 9 is a metallic plate which may be produced, for example, with the aid of stamping andembossing projecting areas intermediate element 9 is situated on closingelement 3 and may be joined to closingelement 3 with the aid of known joining techniques.Planar closing surface 20 is again provided onvalve seat support 2. The fourth exemplary embodiment in particular has the advantage that the closing properties of the valve are changeable in a simple and very cost-effective manner by replacingintermediate element 9. For example, a different embossing of projectingareas intermediate element 9 may be carried out for different engine manufacturers. As a result of this idea according to the present invention of providing anintermediate element 9, a plurality of variants ofintermediate element 9 may be easily preproduced and stored, for example, and then joined without great complexity to the remaining components of the gas valve to provide a manufacturer-specific gas valve. Moreover, a certain level of damping during the closing process exists as a result of the provision ofintermediate element 9 as a disk having embossed projectingareas areas - It shall further be noted with regard to all exemplary embodiments in
FIGS. 1 through 5 described in detail that, in addition to an excellent cold start capability, these also make it possible that lower requirements are placed on tolerances of the individual components. The cost of manufacturing the gas valve according to the present invention is thus significantly reduced. Since according to the present invention exclusively projectingareas elastomeric sealing element 7, there is no risk of undesirable adherence in the closed state of the gas valve.
